Why on earth should any of these writers, none of whom lived in Palestine, even have heard of a minor religious figure with a small following in Palestine, much less mentioned him?
A 'minor religious figure'? According to the gospels, Jesus performed mutliple startling miracles (raising the dead, healing the sick, etc.), attracted a following so great that five thousand people were willing to treck for miles on the off-chance he might speak without even so much as preparing themselves a meal and had people celebrating in the streets as he entered Jerusalem.
Five thousand might not be that much
now but back then it was a good sized army. To suggest that the Jesus of the bible is a 'minor religious figure' not worthy of note is absurd in the extreme.
